Human Body Essay

Introduction.

It is surprising to see how a human body functions with maximum capability. Whether we are talking, walking or seeing, there are distinct parts in our body that are destined to perform a particular function. The importance of each part is discussed in this human body essay. When we feel tired, we often take a rest and lie down for a moment. But our body continues to work, even when we take a break. Even if you are tired, your heart will not stop beating. It pumps blood and transports nutrients to your body.

The human body is made up of many parts and organs that work together to sustain life in our body. No organ or body part is more important than the other, and if you ignore one of them, then the whole body will be in pain. So, let us teach the significance of different parts of the body to our children through this essay on human body parts in English.

Different Systems in the Human Body

The human body looks very simple from the outside with hands, legs, face, eyes, ears and so on. But, there is a more complex and significant structure inside the body that helps us to live. The human body is made up of many small structures like cells, tissues, organs and systems. It is covered by the skin, beneath which you could find muscles, veins, and blood. This structure is formed on the base of a skeleton, which consists of many bones. All these are arranged in a specific way to help the body function effectively. In this human body essay, we will see the different systems in the human body and their functions.

The circulatory system, respiratory system, digestive system and nervous system are the main systems of the human body. Each system has different organs, and they function together to accomplish several tasks. The circulatory system consists of organs like the heart, blood and blood vessels, and its main function is to pump blood from the heart to the lungs and carry oxygen to different parts of the body.

Next, we will understand the importance of the respiratory system through this human body essay in English. The respiratory system enables us to breathe easily, and it includes organs like the lungs, airways, windpipe, nose and mouth. While the digestive system helps in breaking down the food we eat and gives the energy to work with the help of organs like the mouth, food pipe, stomach, intestines, pancreas, liver, and anus, the nervous system controls our actions, thoughts and movements. It mainly consists of organs like the brain, spinal cord and nerves.

All these systems are necessary for the proper functioning of the human body, which is discussed in this essay on human body parts in English.

This essay delves into the intricacies of the human body, exploring its structure, function, and the symbiotic relationship between its various systems.

Structural Complexity

The human body is composed of several levels of structural organization. At the most basic level, we find cells – the building blocks of life. These cells group together to form tissues, which in turn combine to form organs. The organs then work together in organ systems to perform specific functions. The human body comprises eleven organ systems, each with its own unique role, yet they all work in unison to maintain homeostasis.

Functional Dynamics

The functionality of the human body is a testament to the intricate design and coordination of its systems. The circulatory system, for instance, is responsible for the transportation of nutrients, oxygen, and waste products around the body. The nervous system, on the other hand, acts as the body’s control center, sending and receiving signals to and from different parts of the body. The respiratory system facilitates the exchange of gases, while the digestive system breaks down food into nutrients that the body can use. These systems, among others, work in a coordinated fashion to ensure the smooth functioning of the body.

The Symbiotic Relationship

The relationship between the various systems of the human body is symbiotic in nature. Each system relies on the others to function optimally. For instance, the respiratory and circulatory systems work together to deliver oxygen to cells and remove carbon dioxide. The nervous system controls the rate of breathing and heart rate based on the body’s needs. The endocrine system, with its hormones, influences almost every other system, affecting growth, metabolism, mood, and more. This interdependence underscores the complexity and efficiency of the human body.

Adaptability and Resilience

One of the most remarkable characteristics of the human body is its adaptability and resilience. It can adapt to various environmental conditions, from the freezing temperatures of the Arctic to the scorching heat of the desert. The immune system, a complex network of cells, tissues, and organs, defends the body against harmful microorganisms, demonstrating the body’s resilience. Furthermore, the body has remarkable healing capabilities, with systems in place to repair damage and restore function.

In conclusion, the human body is an intricately designed system that showcases the marvels of evolution. Its structural complexity, functional dynamics, symbiotic relationship between systems, and adaptability and resilience are awe-inspiring. Understanding the human body not only allows us to appreciate the marvel that it is but also equips us with the knowledge to take better care of it. Indeed, the human body is a testament to the sophistication and beauty of biological engineering.

Essay On Human Body System

Humans body systems Introduction: The body is made up of many systems that all work together to keep it alive and moving. One of these many systems is the skeletal system. Its functions are that it protects important organs, supports the body, and makes blood cells. The muscular system is another one of the body system and its major structures are muscle tissue and the connective tissue. The functions are allows movements of body parts, works with skeletal system to help us move, maintains posture and generates warmth. The respiratory system’s functions are to breathe, exchanges gases between lungs, and get rid of carbon dioxide from the body. The circulatory systems The functions are to carry digested food, dispose waste that could harm the body, delivers oxygen to the cells and removes carbon dioxide, helps protect the body from diseases, and it provides transport for hormones. The digestive system function is …show more content…

It interacts with the muscular system by connecting all the muscles to the bones by an object called the tendon, which allows the body maximum movement. For example, the biceps muscle is connected to the radius. All muscles connected to the bones have similar function, to flex and contract. An example of this is with the arm. When we “flex” the arm, stress is put on the biceps. When you contract, the stress is placed on the triceps. By contracting and flexing your body, your body can move. The skeletal system also functions with the circulatory system because the red marrow inside of your bones produces red blood cells. The circulatory system then distributes them around the body. These blood cells are important to the body and they could not be circulated if the marrow hadn’t created them. The skeletal system actually works with all systems by protecting them. For example, the skull protects the brain, the spine protects the spinal cord, & the ribs protect the heart and

How To Maintain Homeostasis

Homeostasis is the body's method of keeping internal stability no matter what external influence disturbs its normal functioning (Anna, 2011). And the respiratory system is one of the systems in the body that helps to maintain homeostasis by maintaining pH and regulating gas exchange. The main function of this system is take in oxygen and get rid of carbon dioxide. This system has external respiration and internal respiration. External respiration is a mechanical process that exchange of gases in and out of the body, while internal respiration is the chemical process that breaking down nutrients with oxygen to produce energy.

The Respiratory System

The primary function of the respiratory system is gas exchange, which consists of movement of oxygen into the body and removal of carbon dioxide. To achieve this goal, respiration can be divided and four major functions. First of all, we have pulmonary ventilation, which means the inflow and outflow of air between the atmosphere and the lung alveoli; second, the diffusion of oxygen and carbon dioxide occurs between the alveoli and the blood; after this, these gases are transported in the blood and body fluids to and from the tissue cells. Finally, all these steps are controlled and regulated by respiratory center and receptors. (GUYTON, A.C.; HALL, J.E. 2006)

Theendocrine system is a system in the body that consists of glands liketesticles that are found in males, pituitary glands, ovaries that arefound in females, pancreas, parathyroid, and thyroid glands. Theseglands produce hormones that are responsible for regulating mood,sexual desires, the functioning of tissues, metabolism, andreproduction.

Therespiratory system is primarily responsible for gaseous exchange inthe body. That is, taking in of oxygen gas and taking out of carbondioxide that is done through the lungs. Therefore, the respiratorysystem is responsible for supplying oxygen to all parts of the bodyusing the red blood cells.

Theskeletal system is made up of all joints and bones in the body. Theskeletal system supports and protects soft tissues that are found inthe body. Also, the skeletal system allows joints to move byproviding points for muscles attachment. Furthermore, bones storecalcium, energy, which is in the form of fats, and iron among otherelements.

Thenervous system constitutes of neurons that send out signals betweendifferent body parts. The nervous system is usually divided into twoparts the central nervous system and the peripheral nervous system(Smith et al., n.d). The nervous system controls blood pressure,senses of touch, and breathing among others.

Theexcretory system is responsible for discharging wastes from the body.The excretory system eliminates wastes from the body so as to controlthe process of homeostasis as well as preventing body damage. Organsthat are involved in the excretion process are the liver, kidney,large intestines, and the skin.

Thereproductive system consists of organs found in either males orfemales, and these organs are responsible for procreation. Thereproductive system of a male is made up of testes and penis whilethe female reproductive consists of the vagina, uterus, and theovaries.

Themuscular system usually consists of skeletal, smooth, and cardiacmuscles. The muscular system is checked by the nervous system. Thus,muscular system is responsible for the body movements, bloodcirculation in the body, and maintenance of body posture.

Thedigestive system converts food into nutrients that are easilyabsorbed by the body while the rest is converted into energy. Thedigestive system consists of the alimentary canal that is made up ofthe large intestine, stomach, pharynx, esophagus, stomach, and oralcavity (Smith et al., n.d). In the digestive system, the followingactivities take place: mixing and movement of food, ingestion,secretion, digestion, and absorption.

Theimmune system protects the body from infections caused bymicro-organisms. The main role of the immune system is to keep peoplehealthy and free from diseases. When the immune system fails to workwell, people get infected and suffer from diseases.

Thecirculatory system consists of many networked organs and vessels thatare responsible for the flow of blood to and from cells. Also, thecirculatory system helps in the transportation of oxygen, nutrients,hormones, and gases in the body.

The Muscular System of a Human Body Essay

Works cited.

The muscular system of a human body is the system of organs (muscles) that is responsible for any type of body movement (Muscolino 35). Muscles, of which the titular system is composed, are the tissue that is made of fiber and tissue and can contract and relax (Muscolino 38). The muscular system incorporates not only the skeletal muscular tissue but also the blood vessels, nerves, and tendons, of which muscles are built.

The muscular system is attached to the skeletal one, constituting the locomotor, or musculoskeletal, system (Kisia 110). The number of muscles that it includes exceeds 600, yet the existing classification system allows identifying the key ones (Kisia 112). As a rule, three types of muscles are typically identified:

Also known as the smooth tissue, the said type of muscles is typically associated with the internal organs, in general, and the ones located in the abdominal cavity, in particular (Kisia 116). Visceral muscles are also known as smooth (because of their uniform structure) and involuntary (because it is controlled unconsciously by the human brain) (Kisia 119).

The cardiac muscles are located only in the heart and serve to sustain the blood flow (Kisia 115). The muscle is controlled intrinsically, which is why it is traditionally defined as autorhythmic (Kisia 115).

The identified type of muscle is the only one in the musculoskeletal system that is controlled on a conscious level by the human brain (Kisia 118). The tendon that connects the muscle to a bone allows for the contraction of the former and, therefore, the movement of the body. The examples of a skeletal muscle include the biceps brachii, the triceps brachii, the anconeus, etc. (Kisia 119).

As the definition provided above shows, the movement of the body is the primary function of the muscular system. Furthermore, stability and posture should be mentioned among the characteristics of the human body that the muscular system sustains.

However, the identified function of the muscular system is not the only one. Additionally, the system serves as the means of maintaining posture and allows for blood circulation (Muscolino 74). In other words, while the system is typically associated primarily with lifting a weight, it allows performing a variety of movements as well, not to mention the fact that it helps sustain blood flow. The identified function is performed by the cardiac muscles.

Furthermore, the support of the digestive system can be considered an essential function of the musculoskeletal one. The smooth muscle, which constitutes a range of organs in the digestive system, lines the walls of the stomach. Consequently, when the muscle contracts, the digestive process occurs.

Additionally, the system is also known for helping the human body to produce heat. The identified phenomenon occurs after a movement takes place, therefore, making it possible for the body to function. The production of heat is especially important in the low-temperature environment. Thus, the blood circulation is kept at the required rate even in the cold environment.

Traditionally, when considering muscular diseases, one mentions inflammatory myopathies as the most common type of muscular disease. The identified condition triggers the weakening of the muscles. Dermatomyositis, which also implies that muscles should experience inflammation, is followed by a skin rash. Finally, muscular dystrophies should be listed among common muscular disorders (Kisia 121).

Human Body: A Wonderful Machine

Human body is a wonderful machine. It performs several functions without rest from the birth. Our body continues to work, without stopping for a second. The main organs of the human body are lungs, heart, kidney, liver and brain. These organs work together which are controlled by the brain. Each system carries out a major function, digestive system, excretory system, circulatory system, endocrine system, nervous system, muscular system, etc. All are controlled by the brain. The brain gives us intelligence to use our physical and mental abilities. The body has more than 50,000 living cells of two hundred different types. These cells include neurons (nerve cells) and glands (specialized cells). The hormones and enzymes are produced and secreted by these glands. Various types of cells perform different functions. Cells doing similar job are grouped to form tissues. The tissues group together in a special manner to form organs.

The human body is covered by the skin. Skin is a flexible covering which protects the body. It keeps water and harmful germs out. It is war resistant. The body’s strong internal framework (skeleton) is made of 206 bones. These are connected at the joint, such as in legs. These joints help us to move. The backbone supports the head and limbs and protects the spinal cord. Between the skeleton and skin there are about 500 muscles. Nerves spread from the brain to all part of the body. They carry signals in the form of tiny electrical impulses, the sense organs, namely eyes, nose, ears, tongue and skin, pass the messages to brain through nerves. They take the instructions from brain to muscles. The brain automatically controls breathing, heart beat, digestion, etc. The body keeps on growing. The peak of physical growth is reached at about 18 to 25 years of age. When we grow old the skin becomes wrinkled and less elastic. The joints become inflexible, muscles loose, bones become weak. At the climax of life, the body gives up and death occurs.

Human body is the most valuable gift of God to human being. A healthy body contains a healthy brain. A healthy brain contains a healthy soul. As such, it is very important to take care of our body. For this regular exercise, control over eating habits, cleanliness of body and discipline are essential in daily life.
